What has caused this upside down world of Isaiah?
The inspired prophet clearly gives the answer.
Because they say "He made me not" (Isaiah 29:16).
Because they have (Isaiah 24:5):
1. transgressed the laws
2. violated the statutes, and
3. broken the everlasting covenant.
This answers the question of WHY?, but HOW?
"HOW" is best answered by this article by William S. Lind, published here or internally here.
